Gabriel Rouchon, CEO of water-cooling experts Swiftech, has revealed that AMD is planning to release a revised PCB for the Cayman cards HD 6950 and HD 6970. Following a delay of 3 weeks, AMD rushed “initial release” products to the market, with a “revision” coming shortly. The changes are hinted to be related to VRM and power components, being major enough to warrant a redesign for Swiftech’s waterblock.

changes are hinted to be related to VRM and power components, being
major enough to warrant a redesign for Swiftech’s waterblock.

Interestingly, it is suggested that the TI DrMOS shortage we reported in November might have forced AMD to opt for Volterra DrMOS. Rumours suggest that AMD will revert back to the TI DrMOS for the “revision” PCB.

This revision might also give AMD the opportunity to hard disable BIOS unlocking of SIMDs from 6950 to 6970.

Exactly how major (or minor) this revision is, and how it will benefit the end user, remains to be seen.
